330 Mr. E. Meyrick on the classification 



Mnesictena fla/oidalis, Dbld. 



Margaritia flavidalis, Dbld., Dieff. N. Z., ii., 287 ; 

 M. quadralis, ib., 288 ; Scopida dipsasalis, Walk., 

 796 ; Botys otagalis, Feld., cxxxiv., 35. 



Variable in brightness and depth of colouring. 



Auckland, Taranaki, Napier, Wellington, Christchurch, 

 and Dunedin, New Zealand ; probably generally abundant 

 throughout the North and South Islands, from January 

 to March. 



Mnesictena notata, Butl. 



Scopula notata, Butl., Cist. Ent., ii., 493. 



Arthur's Pass (3000 feet) and Dunedin, New Zealand ; 

 a local species; several specimens in January. 



Nesaecha, n. g. 



Forehead flat, oblique. Ocelli present. Tongue well developed. 

 Antennae two-thirds of fore wings, in male rather stout, fihform, 

 evenly ciliated {^), rough-scaled above. Labial palpi very long, 

 straight, porrected, 2nd jouat with dense evenly projecting scales 

 beneath, terminal joint rather long, exposed, with shorter pro- 

 jecting scales beneath. Maxillary palpi moderate, dilated with 

 loose scales towards apex. Posterior tibiae with outer middle-spur 

 in male one-sixth, in female one-half, outer end-spur in male one- 

 thu-d, in female one-half of inner. Abdomen elongate, in male 

 with moderate anal tuft ; valves exserted. Fore wings with vein 

 11 moderately long, obhque. Hind wings hardly broader than 

 fore wings ; 3 remote, 4 and 5 somewhat approximated at base, 

 7 out of 6 rather near origin, anastomosmg with 8 to one-half. 



Of doubtful affinity, but I think there is a relationship 

 with Mnesictena ; the form of wing is i)eculiar, but can- 

 not be regarded as generic. 



Nesarcha hyhreadalis, Walk. 



Scopida hyhreadalis (hyhreasalis) , Walk., 797 ; Scopula 

 paronalis, ib., 797 ; Adena xanthialis, ib., Cr., 

 198. 



^ , 2 , 24 — 31 mm. Head and thorax varying from light 

 ochreous to fuscous, white at base beneath. Antennae ochreous, 

 spotted with dark fuscous above. Abdomen whitish ochreous,
